Here are some ideas if you are in a tight budget for lighting. Just played with some wood, pvc, aluminum bars and screws.
For the par38. I recycled some aluminum casing which i used for my old FW tanks. Modified the holes, wirings. Used wood and aluminum bars for the base. I also installed 3 fans for the purpose of cooling the pars and the water. The fan on top is intended for the sump.
Here are they in action.
